Re: 2003 300 HPDI wiring issue(Need Help)
the blinking is most likly incorrect dip switch settings, the alarm may be water detect, unplug the water detect at the engine filter and double check your dip switch settings, also insure oil is transfering from the remote tank to the main tank.
engine tank low you get an alarm, engine tank low and remote full you get 3 flashing bars and an alarm.
